The Fourth Amendment prohibits unreasonable searches and seizers and requires any warrant to be judicially sanctioned and supported by probable cause.

The purpose of this amendment was so people could feel protected and know they could keep their stuff safe while government was out there doing their jobs. This was proposed because it deals with protecting people from the searching of their homes and private property without properly executed search warrants. This amendment was added on December 15, 1791 and was ratified on September 28, 1789. Some changes that were created after it passed were you had to get government authority or a warrant to go through peoples belongings.
